How To use the Stack Profile tool to create a topographic profile

  • Input = an existing line feature class or a line drawn using
    the pencil tool on the tool.

  • Profile Target = elevation raster

    • The tool output is a table

  • Open the table (it's at the bottom of the Contents pane).

    • The important fields are FirstDist and FirstZ.

    • FirstDist is the distance along the line that you drew.

    • FirstZ are the elevation values along the line.

  • Close the table.

  • Right click the table and select 'Create Chart – Line'

    • Date or Number: FirstDist (first distance)

    • Aggregation: sum

    • Numeric field: FirstZ

  • ProTip: If you put both LiDAR data sets in the Stack Profile targets, you can show profiles
    across the pre- and post-data on the same graph.
